You could do it with ICE kinematics, but I think this might be easier: 1. Apply a path constraint to get nice things like tangency and up vector for free. 2. Remove the animation on Path %age. 3. Apply an ICE tree to calculate the percentage yourself: get current time (make sure to turn Global on), multiply by desired speed, divide by curve length (this is why you can't do it with a simple expression), multiply by 100 for the percentage, and set self.kine.pathcns.perc.
gray From: [email protected] [mailto:[email protected]] On Behalf Of Ponthieux, Joseph G. (LARC-E1A)[LITES] Sent: Wednesday, June 19, 2013 10:16 AM To: [email protected] Subject: velocity I'd like to set an object on a path using velocity, or something similar to velocity at least, as the means of propagation along the path. The idea is to animate a bunch of different objects, while on different paths of random lengths, so they all appear they are going the same speed regardless the path length. I know that I can use velocity as a factor on particles, but these need to be models animated on paths. Is this possible?
